Use revlogng and inlined data files by default

This changes revlog specify revlogng by default.  Inlined
data files are also used unless a flags option is found in the .hgrc.
Some example hgrc files:

[revlog]
# use the original revlog format
format=0

[revlog]
# use revlogng.  Because no flags are included, inlined data files
# also be selected
format=1

[revlog]
# use revlogng but do not inline the data files with the index
flags=

[revlog]
# the new default
format=1
flags=inline

#!/bin/sh

cd t
hg init
echo a > a
hg add a
hg commit -m "test" -d "1000000 0"
